At Thanksgiving Five-0 investigates the murder of philanthropist George Parks, seemingly killed as witness to a robbery on his own property, where only a huge, rare, millions-worth koa tree was stolen. Upon arriving at the suspected gardener's address, the team finds the robbers killed but the wood remains there, except when piece containing a large cavity. George's family is associated with a German backpacker's suspicious disappearance years ago, which proves the homicidal key with a noble twist. Junior and Tani investigate a robbery at his parent's house, and discover that the robber stole a hidden 'treausre box', including his estranged father Natano's Purple Heart medal. Junior suspects his childhood best friend and informal foster brother Owen Ocampo, now a junkie, who confesses, but didn't pawn the Purple Heart, not forgetting his friendship with Junior. He later accepts Junior's ultimatum-offer to go to rehab instead of prosecution. Reconciled, Junior invites his parents to the Thanksgiving celebrations at McGarrett's house, where Danny has moved in on account of another mold problem.
